Explosion-proof sound sirens DB3B
Art. DB3B
The DB3B is a high-power explosion-proof sounder that replaces the existing DB3 model with improved functionality and performance.
Certified for use in a wide temperature range from -55°C to +85°C, the explosion-proof housing is constructed of fiberglass-reinforced polyester with a durable thermoplastic horn, making the unit corrosion-resistant and providing a pleasing appearance.
The DB3B can deliver a sound level of 122 dB at a distance of 1 m and comes with a selection of pre-recorded audio tones. The device features a built-in volume control, making it ideal for applications requiring a quieter sound.
The unit is available with various control options, ensuring compatibility with a wide range of control methods and PLCs.
The standard DC-powered device has three audio signal stages. Each stage has 28 available audio signals, which can be selected independently. The device is controlled by reversing the polarity of the power supply (two-stage) or by applying a common negative and switching between multiple positive power sources.
The DB3B model demonstrates its versatility with the additional ability to operate with a common positive power supply and switchable negative terminals. The DB3B's audio signal levels can also be adjusted using the free contacts on the control panel.
The line's versatility also lies in its wide supply voltage range. The short horn version is a worthy addition to the line, offering high SPL in a compact enclosure.
